## Discrepancy

FLIGHT 6255 - FLL-RIC - SHORTLY AFTER BEGINNING TAXI OUT, THE BRAKE PEDAL WAS DEPRESSED WITH NO BRAKE ACTUATION.  THE BRAKE PEDAL WAS FULLY DEPRESSED AND APPROXIMATELY 5 SECONDS LATER, THE BRAKES ABRUPTLY FULLY APPLIED.  THE AIRCRAFT WAS BROUGHT TO A COMPLETE STOP AND WAS TUGGED BACK TO THE GATE.  THE EMERGENCY BRAKE FUNCTIONED PROPERLY AND A BRAKE DEGRADED MESSAGE APPEARED ON EICAS.  MAINTENANCE FOUND A LOOSE CONNECTOR ON THE BRAKE CONTROL UNIT.  RESECURED ALL CONNECTIONS AND TAXI CHECKED THE AIRCRAFT.  TAXI CHECK AND OPS CHECK GOOD.
